This 4-inch metal duct connector is a simple but essential piece if you’re extending or connecting dryer vent pipes.

It’s made from galvanized steel, so it’s rigid, rust-resistant, and won’t crush like foil or plastic flex duct.

The coupler lets you join two pieces of 4-inch round metal pipe securely, creating a solid connection that won’t leak air or lint.

Installation is easy—just slide it over the ends of your pipes and secure with steel clamps (sold separately).

The snug fit and rigid construction ensure a firm joint that stays put.

It’s manufactured from heavy-gauge galvanized steel, so it holds up to heat and vibration without deforming.

While it’s primarily used for dryer vents, it’s also handy for bathroom exhaust fans or range hoods where you need to connect rigid duct sections.

A basic but crucial part for any ducted exhaust system.

Solid, simple, and affordable.
